IMPROVEMENT IN CdTl'ON-GIN FEEDERS.

Specification raaag M of Letters Patent No. 194.68 i, dated August 28,1877; application filed Ju y 6; 1877.

To an whom it may concern.-

y p Be it known that I, JAMES W EILIJIOZLT, of

of Alabama, have invented a new and useful Improvement in GottomGiiiFeeders, ofwhieh the following is a specification, reference beh to thewQm -ai i e d wmes The invention relates to an improvement incotton-gin feeders; and consists in the mechanism hereinafter more fullydescribed, the object being to furnish a simple iaiid effectual means offeeding cotton to theggin Figure l is a central vertical longitudinalsection of a device embodying the elements of the invention. Figs. 2 and3 are obverse and reverse detached plan views of the rear portion of theelevator. Fig. 4 is a side elevation of the elevator-rake. Fig. 5 is anend view of wheels E F.

In the accompanying drawings, A represents the standards, in the upperends of which is mounted the elevator-frame B on the axle or trunnion D,one end of which is provided with the pulley or band wheel E adjacentthe standard A, and at its extremity with the similarly-constructedwheel F, which may be furnished with an ordinary clutchton its innerface in order to communicate motion to the said wheel E, which isconnected by a band to the wheel H mounted on an axleinthehanger 1,wherein is also mounted the pinion L. This pinion meshes with thegear-wheel M secured on the axle of the drum or picker-roller N, whichhas bearings on opposite sides of the elevator-frame B at the rear endof same and immediately above the endless apron P. The elevator frameand apron incline upward a suitable distance, and then downward, asshown,-to efl'ectively consummate the object of the invention, as willbe observed hereinafter. Ateach end of the frameB and slightly removedfrom its center is furnished a roller, R, upon and over which the apronor carrier belt 1? is placed, the middle and rear rollers beingpivotally secured, and the front one adjustably, the ends of its axlebeing furnished with the threaded bolts S, which move in the guide-slotsT and protrude beyond the ends of same, where they are provided withsetp y 7 H screws V, Prattville, in thecountyof Anta'ugag d Stat j It isobvious that when the screwsare Fworked toward the end of theelevatonframe" gtlie bolts S are drawn frontward, thus making taut theapron l, and when the screws receive a reverse movement the tension ofthe apron is loosened.

The end of the axle of the picker-roller ioppusite the gear-wheel Misfurnished with a crank, W, the, short arm of which travels in the slotof the oscillating bar X mounted on the axle of the front roller R, andsupplied on its inner face with the pawl a, which engages the teeth ofthe ratchet-wheel I), also mounted on the shaft of the front roller R,and in close relation to the bar X. The crank W is connected to thecrank (1 formed on the end of bar 6 by the draw-rod f, which insuresunto the two cranks a corresponding movement. The bar 0 is bent downwardat suitable points, making a short turn, and thence upward, forming theguides g, as shown, in which the threaded bolts h are placed, theirenlarged ends being on the rear of the guides, and their front endsextending forward, where the boardi is placed on them and prevented fromescaping by the set-screws k, whereby the board can be adjustedvertically, or entirely detached, without affecting the said guides orbar 6. v

To the lowdr edge of the board 13 is hinged the rake l, which, when theboard is secured to the bar e, receives a movement similar to that ofthe crank 01, and is employed to assist in conveying the cotton to thepicker-roller, and at the same time to spread it out evenly in a sheetor bat, so that the same can be delivered to the cotton-gin (whichisimmediately in front of the feeder) in a suitable form.

The upper and rear portion of the drum or roller N may be covered withgauze wire or other perforated material, as shown, so that a space isallowed between the lower edge of the same and the elevator-belt toallow the passage of the cotton to the gin.

It is evident that the elevator, being pivotally mounted on the axle D,can be inclined on any desired angle, and thus permit the operator toclean or adjust the mechanism at will. The rear end of the frame B restsupon the standards m, which may be secured to the floor of thegin-house. I

The saw-shaft of the cotton-gin is connected with and communicatesmotion to the wheel F, which, in turn, imparts its motion to the wheel Ethence it is conveyed through abelt to the wheel H, pinion L, wheel M,and pickerroller N. This further communicates the motion through thecrank 01 to the mechanism operating the rake, and to the pawl a andratchet b, which cause the rotation of the elevator-apron P.

It is also evident that when the oscillating bar X is carried forward itdraws the pawl a with it, and when that movement is reversed it pushesthe pawl rearward, and, as the end of the said pawl is engaged by atooth of the ratchet, it will force the same and the front roller R torotate. This gives the endless apron a similar movement, and thus causesits operation.

' The cotton is placed upon the apron at the front end of the feeder,and is carried upward under the rake and over the roller N at the rearof the frame, where it is delivered to the gin. At the same time anydirt that may be in the cotton will pass on the downward incline of theapron beneath the drum N, and beprecipitated to the floor of thegin-house.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The elevator-frame B, provided with an endless apron having adouble incline, and pivotally mounted upon the axle D, substantially asset forth.

2. The drum N, provided with the crank W, operating in the slotted barX, having the pawl a, which engages the ratchet b, in combination withthe draw-rod f, crank d, and rake l, substantially as shown anddescribed.

3. A cottongin feeder mounted on trunnions placed at or about its centerof gravity, substantially as set forth.

4. The combination of the bar a, board i, bolts h, set-screws k, andrake l, substantially as specified.

5. The apron P, having a double incline in combination with the drum Nand rake Z, substantially as expressed.

In testimony that I claim the foregoing improvement in cotton-ginfeeders, as above de-. scribed, I have hereunto set my hand this 28thday of June, 1877.
